i found a mikuni corp carb at the swap meet no numbers or any id marks. it has a spigot mount 14mm a big bell 62mm with a block off choke a 1.5 slide pilot jet and a petcock r/s and a screw plug to remove the main jet. looks like a nt. my son's not here so no pic's today. 14mm, my motors 48cc with a sbc chamber think it might work? i need a mag glass to see jet sizes and it stinks so im sure the pilot is clogged, worth the trouble? i dont know if the 48's and the 66's are the same carbs
